How to Add EC2 Instance to ECS Cluster Using AWS Node SDK
I am trying to programmatically create an ECS cluster with an EC2 instance in it. As I understand it, I must first create an ECS cluster than an EC2 instance and then register the instance using this method:
http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/ECS.html#registerContainerInstance-property
How am I supposed to do this? What arguments are required? How to get instanceIdentityDocument and instanceIdentityDocumentSignature?

I would use custom EC2 instance data to launch the instance directly to the ECS cluster. This is the user data you want to use:
#!/bin/bash
echo ECS_CLUSTER=your_cluster_name >> /etc/ecs/ecs.config
See the AWS docs for details . You can also use this custom data in the auto scale launch configuration.
Also, it might be worth looking at the languages in which the provisioning infrastructure is done, such as Terraform (also for AWS) or CloudFormation (specifically for AWS).
